+// OpenTelemetry Initialization
+// ===================================
+//
+// The OpenTelemetry SDK must be initialized BEFORE any other modules are imported.
+// This ensures that instrumentation can correctly patch the necessary libraries
+// and capture telemetry from the very beginning of the application's lifecycle.
+//
+//import { NodeSDK } from '@opentelemetry/sdk-node';
+//import openTelemetryConfig from './open-telemetry.config.json'; // Assuming this config file exists in your new project
+
+// const openTelemetry = new NodeSDK(openTelemetryConfig);
+
+// try {
+//     openTelemetry.start();
+//     console.log('✅ OpenTelemetry SDK started successfully.');
+// } catch (error) {
+//     console.error('❌ Could not start OpenTelemetry SDK:', error);
+//     process.exit(1);
+// }
+
+// // Gracefully shut down the OpenTelemetry SDK on process exit.
+// process.on('SIGTERM', () => {
+//     openTelemetry
+//         .shutdown()
+//         .then(() => console.log('➡️ OpenTelemetry tracing terminated.'))
+//         .catch((error) => console.error('Error terminating OpenTelemetry tracing:', error))
+//         .finally(() => process.exit(0));
+// });
